  • To Dispose or Not To Dispose? Here is the question.

    -

    One of the best articles that I’ve read so far about the importance of properly disposing SPWeb and SPSite objects has been written by one of my favourite SharePoint bloggers Stefan Gossner and can be found here.

    Unfortunately there are still some conflicting messages about what to do with SPWeb instances creates via the SPSite.RootWeb property. According to Stefan we need to call dispose but other people from Microsoft are saying the opposite as you can see here.

    So the search continues….

  • SharePoint Lessons Learned – Clearly Define a Deployment Baseline (Part 2)

    -

    In part 1 of this post I’ve talked about the principles behind the creation of a Deployment Baseline during the development of SharePoint based applications. In this post I’m going to talk about how we, at Collaboris. normally group and categorise the different artefacts to create this baseline.

    This post assumes that you are familiar with the concepts of SharePoint Features, Site Definitions and Solution Packages. For a primer on these concepts please refer to this page on MSDN.

    There has always been a lot of debate around the best way to deploy SharePoint applications. Some people do not like Site Definitions or Features and prefer to use Site Templates (.stp), others prefer xcopy deployment and others like me stick with Features and Site Definitions deployed using Solution Packages. I’m not going into that debate here, I’m simply going to describe the approach that we have been taking for the last few years without any regrets.

    Like I’ve mentioned on the first post I’m strong believer in using the SharePoint Features and Solution Framework for the delivery of SharePoint applications. We normally try to deploy most of the artefacts via Features which are activated via Site Definitions and deployed using ...

  • SharePoint Lessons Learned – Clearly Define a Deployment Baseline (Part 1)

    -

    One of the major lessons that I’ve learned so far with SharePoint development is how important it is to clearly define your Deployment Baseline from very early stages in the development lifecycle. In part 1 of this blog post I will describe the concepts behind this Deployment Baseline and in part 2 I will describe how in Collaboris we apply them to the development of SharePoint applications.

    A deployment baseline is a clear definition of the artefacts that are going to be built and deployed when creating a new application. These artefacts should be catalogued and grouped based on their purpose, functionality and on how we plan to deploy and maintain them once the application is live. This baseline will also help to clearly define the different areas of responsibility within the team.

    Imagine that you are developing a new Web Content Managed application where the development team is responsible for the creation of all the technical artefacts (ASP, HTML, CSS etc) and the business team is responsible for the creation of content (pages and documents). In this scenario it will make sense to create two separate packages; one for the technical artefacts the other for the content artefacts. These ...

  • The SharePoint Deployment Maturity Model

    -

    MOSS has been the most successful server product Microsoft ever released. Sales are growing much faster than Microsoft ever expected and apparently the UK is outstripping worldwide growth (for more see this). Unfortunately this quick growth is also highlighting one of the major problems that everyone seems to be struggling with - deployment. I've been working with MOSS since Beta 2 and I have debated this issue with other colleagues and we are all in agreement: deployment is one of the biggest pains on any SharePoint project. It's one of the areas that will give you more problems and cost you more money. What is curious is that all companies adopting SharePoint seem to go through the same evolution path. Finding a way to measure where my customers are on this path gives me a good idea on the challenges that I will be facing when moving their projects forward. The kind of measure that I'm talking about it's called a Maturity Model so I called it the Deployment SharePoint Maturity Model (SDMM). 

    Like the Capability Maturity Model (CMM) I divided the SDMM is divided into 5 levels (except for level 4, I have used the same names ...

  • How to free your Data View/Form web part (DVWP/DFWP) from those nasty GUIDs

    -

    Ever wanted to use the same page layout containing a DFWP, and bind it to a local site list in each site of your site collection ?

    Ever want to be able to deploy a page with a DFWP to a different server?

    If you ever tried any of the above using SharePoint Designer you would have found problems because, by default, SharePoint Designer binds the control to the list instance using the list instance GUID. To resolve this we need to replace the GUIDs by the list name. The steps to do this are:

    1. On the attributes of the DataFormWebPart element replace the attribute ListName="{GUID}" by ListName="LIST_NAME" where LIST_NAME is the name of the list that you are binding to.
    2. Go through all of the DataFormParameter elements and replace:

      <WebPartPages:DataFormParameter Name="ListID" ParameterKey="ListID"

      PropertyName="ParameterValues" DefaultValue="{GUID}"/>


      with:

      <WebPartPages:DataFormParameter Name="ListName" ParameterKey="ListName"

      PropertyName="ParameterValues" DefaultValue="LIST_NAME"/>

    3. Go to the ParameterBindings element and replace

      <ParameterBinding  Name="ListID"  Location="None"  DefaultValue="{GUID}"/>

      with:

      <ParameterBinding  Name="ListName"  Location="None"  DefaultValue="LIST_NAME"/>

    This should give you a GUID free DFWP that can be placed on a page layout used by multiple ...

  • SharePoint Lessons Learned – Don’t forget to use proven design patterns and practices

    -

    SharePoint should be seen as another layer in the technology stack that your code will interact with. But just because you are using this layer you should not forget to follow good and proven design practices. The following points describe some of the principles that sometimes seem to be forgotten when using SharePoint:

    1. Create a data access layer to access your lists.

      After all you would be doing this if you were programming against a database table so why not do the same for a SharePoint list. The last thing you want is to have several components of your application accessing the same list in several different ways. If the list schema, name or location changes then you would need to change the code in every component that uses that list (this could be acceptable for small proof of concept applications but not for enterprise applications). In a future post I'll be giving an example of designing and coding a simple SharePoint data access layer.
    2. Use SharePoint lists to store configuration data. Create a configuration site, on your site collection, containing all the configuration lists

      Before SharePoint all configuration needed by you applications resided in a data store (normally ...

  • Requirements, Requirements, Requirements...

    -

    Those are the three most valuable artefacts of a project. Requirements should drive most (if not all) activities in a project. A project should be architectural centric and requirements driven... We have all heard these clichés before but how exactly does one manage requirements in an iterative process?

    How do we make sure that all team members are rowing the same way?

    Supporting Iterative Development Through Requirements Management gives a good insight on how effective requirements management can be accomplished in an iterative process - in this case using the Rational unified Process (RUP). Even if you are using another iterative process (like SCRUM or XP) the article should give some good ideas.

    If you are not using an iterative process then forget about the article and read "Why should I be using an iterative process" instead.

  • Unit testing made easy

    -

    Unit testing has taken a new momentum with the rise of the agile development practices. NUnit is a fantastic and simple unit-testing framework for all .Net languages but if you used it before you have probably come across the difficulty on how to isolate the unit that you want to test. NMock was created to address this issue. Mock Objects to the Rescue is a very good article on how to use this useful tool.

    If you have not used NUnit before you will find a good introduction on the Test Driven C# msdn article.

  • To Interface or not to interface? Here is the question

    -

    Isn't it funny that, suddenly, interfaces do not seem to be in fashion in the .Net world anymore ?


    In the not so good old days of COM there wasn't an option - if we wanted a component we had to have at least one interface. The abstract server pattern was alive and kicking and the advantages of separating a service contract from its implementation were clear to all (at least to the ones using OO languages). In those days there was a clear distinction between a component (something providing services trough an interface) and a class.


    Now, in the new world of .NET, we can have classes, in different assemblies, talking directly to each other. Call me an old fashion geezer but I still strongly believe in patterns like the Separated Interface and Factory (from one of my favourite books Agile Software Development). Perhaps I should go back to my perforated cards...
